A little help here is needed on my refresh rate for my monitor.
(I am starting to twitch like a weapons of mass destruction test dummy after looking at this monitor for more than 2 minutes. )

I have read a heap of posts - and I ran redhat-config-xfree86 in an effort to improve my refresh rate. I am running a no-name (Higrade Notino R5400) laptop at 1024 x 768 - so I went for the generic laptop display.
After chosing many different options, other than changing my resolution to 800x600 sometimes, none of these improved my refresh rate.
I have posted my XFree86config file here - can someone point out exactly what I need to change to increase my refresh rate?

# To disable the XKEYBOARD extension, uncomment XkbDisable.
# Option "XkbDisable"
# To customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults). For example, for a non-U.S.
# keyboard, you will probably want to use:
# Option "XkbModel" "pc102"
# If you have a US Microsoft Natural keyboard, you can use:
# Option "XkbModel" "microsoft"
#
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
# Option "XkbLayout" "de"
# or:
# Option "XkbLayout" "de"
# Option "XkbVariant" "nodeadkeys"
#
# If you'd like to switch the positions of your capslock and
# control keys, use:
# Option "XkbOptions" "ctrl:swapcaps"
# Or if you just want both to be control, use:

Didn't you try the advanced tab. It will allow you to enter the refhresh rates for your monitor.

Yes, I tried to enter increasing numbers (from 60 up to 75) in the Vertical Refresh rate, but there was no change at all in the flickering. I used these options under the Generic Laptop display - 1024X768....

any ideas?

Sorry, I am not all that familiar with new newest XFree86 version.
There is an xfree86 link here, worth a look.

When you said you changed the refresh rate, if you know for sure what your screen can handle, did you try forcing the lower limit to be the upper limit of your screen?

did anybody get this issue solved? Im having exactly the same problem but with a Sharp PC-FS2518 laptop which appears to use the same graphics chipset. After a basic install of redhat, the graphical logon screen looks fine, i installed blackbox, and once i log in and the window manager loads, the screen gets pretty flickery. The specification sheet which came w/ the laptop doesnt specify what refresh rates the screen supports.

simonbell,

I didnt end up getting this fixed, just changed my background to black so I didnt get the flickering.

sorry mate

cheers

timboi? any relation to timboii? or timbo?
